I don't want to switch locale dynamic. And actually switching locale in pure gwt isn't a problem. I don't know how to do it with Ext-GWT native widgets like for example paging grid. It has tooltips on the paging toolbar buttons: "Next Page", "Last Page" etc. And i need to translate them.

Common folks! I am certainly not the first one to deal with this - a lot of widgets in GXT have some kind of text in english. Isnt there a possibility to switch the locale besides editing each Widget.getMessages().set*() message?
